Styrene-based thermoplastic resin composition, production method of styrene-based thermoplastic resin composition, molded article, and production method of molded article

Abstract

A styrene-based thermoplastic resin composition includes: (A) a graft copolymer obtained by graft-polymerizing, in the presence of a conjugated-diene-based rubber, (a) a monomer mixture containing at least an aromatic vinyl-based monomer, a methacrylic acid ester-based monomer, and an acrylic acid ester-based monomer; and (B) a vinyl-based copolymer obtained by copolymerizing (b) a monomer mixture containing an aromatic vinyl-based monomer, a methacrylic acid ester-based monomer, and a vinyl cyanide-based monomer, and containing substantial no acrylic acid ester-based monomer.
